Working in France with a Schengen residence permit

For my ADEF application I had provided an Italian document stating my identity and on which was noted my Pakistani nationality… But in Italy I had had an unlimited residence permit! I didn’t think I was in France illegally! I was told that if I could provide an official letter that stated that I had the right to work anywhere in Europe then they would have unblocked my application.

I went back to Italy and saw the social worker who dealt with my case at the village town hall… but they all told me that that type of document did not exist. They did, however, confirm that with the visa delivered by Italy I most certainly had the right to work anywhere in Europe.
